WVESLEY W'ALTON, AND ISAAC WALTON, ALL OF CHECK-ROW PLANTER.

SPECIFICATION forming part of LettersFatent No. 289,696, dated December4, 1883. Application filed July 5, 1883. (No model T0 (ZZZ whom it ntctyconcern Be it known that I, LEVI J ODELL, a citizen of the UnitedStates, residing at Fairbury, in the county of Livingston and State ofIllinois, have invented a new and useful Check-Row Planter, of which thefollowing is a specification, reference being had to theaccompanyingdrawings. 7

This invention relates to check-row planters; and its object is toprovide a device of this class possessing superior advantages in pointof simplicity, inexpensiveness, durability, and general efficiency.

In the drawings, Figure l is arear perspec tive view of the frontportion of a corn-planter, showing my check-row mechanism in position.Fig. 2 is a detail perspective View of the gear-wheel mechanism. Fig. 3is a sectional viewtaken through the rotary shaft that carries thecrank-disk. Fig. 4 is a detail sectional view of the crank disk andpawl. Fig. 5 is a detail perspective view of the connection of thetappet-wire fork with the rockshaft.

Referring to the drawings, A designates the frame of the corn-planter,on which are mounted the seed boxes or hoppers B B, through which worksthe transverse reciprocating slide 0 in the usual manner.

D is a cross-bar that is secured on top the seed-boxes, and is providedwith cross-pieces E E, arranged one at each end, and having bearings F Ffor the transverse main rockshaft G, to the ends of which are securedthe forks H H, that are operated by the tappetwire to actuate the saidrock-shaft.

The foregoing mechanism may be of any ordinary or suitable construction.

The rock-shaft G has a bearing in a plate,-

shaft will be carried around by the loose 4 wheel M. IVhen the tappetdisengages from the fork H, the shaft G is brought back to its normalposition by action of a spring, Q, on the fork, and the wheel J engagesthe wheel Min the opposite direction; but during this movement the wheelM will be merely turned on the shaft K and the pawl will slide over theface O,while the said shaft K will remain stationary until by theoperation of the next tappet upon the forks it will be turned again bythe Wheel M engaging the pawl. By means of this mechanism the rock-shafthas onlya rock motion back and forth, while the shaft K has a rotaryintermittent motion. This rotary intermittent motion of shaft K ofcourse turns the crank-disk L, the pin R of which entersalongitudinally-disposed slot, S, in the top end of a rock-lever, T,that is pivoted on a bracket, U, projecting from the cross-bar D, and ispro vided at its lower end with a slot, .V, that is connected with aslotted standard, .W, on the seed-slide G by a pin, X. By the movementof this rook-lever T, caused by the intermittent rotary movement of thedisk L, the seedslide is-reciprocated.

The operation and advantages of my invention will be readily understoodand appreciated. It is exceedingly simple and inexpensive inconstruction, and operates with superior efficiency.

The rock arms or forks IIH are preferably arranged to loosely turn onthe rock-shaft G, which latter is provided with end pins, Y, that engagea shoulder, Z, on the forks, so that the rock-shaft will be turned byaction of the forks. In this way the forks on therock-shaft will operateindependently and alternately, as one will remain stationary while theother i'sin engagement with the pin to turn the rock-shaft. Thecrank-disk L is preferably provided with a ratchet-face, A that isengaged by a gravitypawl, B to retain the rotary shaft from backwardmovement while the rock-shaft is returnmg.

I am aware that check-rower mechanism has been heretofore constructedwith a rotary shaft adapted to transmit its motion to reciprocate theseed-slide and operated by the rock-shaft,

the movement of the rotary shaft being interagainst rotary movement onthe shaft, and

having the inner ratchet-face,the gear M, loose- 2o 1y arranged on theshaft between the disk I? and bar D, and having the outer ratchet-face,the spring acting on disk I to force it into engagement with gear M, thepawl B engaging portion A to hold shaft K from reverse 25 movement, andmechanism acting upon gear M to turn it alternately in oppositedirections, substantially-as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in 30 presence of two witnesses.
